An ultra-short Chayote-like compact electronic energy-saving fluorescent lamp comprising, in one embodiment, a base, an upper cover, a lower cover, a luminous tube of the Chayote-like lamp and an electronic ballast. The luminous tube of the Chayote-like lamp is formed by bending several U-shaped unit luminous tubes at certain curvature into finger-shaped luminous tubes, and by connecting and assembling the finger-shaped unit luminous tubes according to the shape of a Chayote using the method of bridge connection. The Chayote-like lamp has the advantages of ultra-short structure, higher luminous efficiency, higher reliability and other benefits. The Chayote-like lamp of the present invention can be used for general illumination, although it is preferably used in combination with the lamps and lanterns having covers.
